During a game in which I had both the destination tickets of Madrid-Dieppe and Cadiz-Stockholm, my opponent blocked me by building Pamplona to Madrid. For my last go in the game I built a station on Pamplona.

I owned Madri-Cadiz and all the other tracks required to get to Dieppe and Stockholm from Pamplona, however when the score was calculated it said that I had failed both those tickets. It was as if the station had done nothing.
